A major amusement park in Kuwana right on the border with Aichi Prefecture. Along with Nabana no Sato, it is part of the Nagashima Onsen entertainment and leisure area.

Opened in 1966, it is arguably the 2nd biggest amusement park in all of Japan behind Fuji-Q Highlands. There are about 45 total rides with 10 roller coasters. The water park currently holds a record for highest density of water slides in a given area, and makes the park especially popular in the summertime.
